SPECIFICATION forming part of Letters Patent No. 407,376, dated July 23, 1889.

Application filed March 20, 1839.

To all uzoI/I, fr muy concern.-

lle it known that I, JOHN SMITH, of Kansas tity, Jackson county, Missouri, have invented certain new and useful Improvements in Fire and Tater lroof Ceilings, of which the following is a full, clear, and exact description, rcferenef.- being had to the accompanying drawings, forming a part hereof.

'.lhis invention relates to certain improvements in [ire and water proof ceilings, having for their object readily to extinguish and prevent the communication of fire from one iloor or story to another of a building: also, to permit of thedrainageof waste waterafter the extinguishmentof the tire; and to these ends the nature of the invention consists of the combination of the parts and their construction, as will fully appear from the followingl description, in whieh- Figure l is a broken-away perspective and partly-sectional view of a portion ot a brick structure enibt'idying my invention. Fig. 1s a detailed perspective partly sectional view of a feature of my invention. Fig. is a sectional elevation, on a somewhat red need scale, taken through Fig. i. Fig. t is an enlarged detailed perspective partly-sectional view of a feature of my invention, and Fig. 5 shows perspective views of the two forms of suspenders or hangers used in connection with the brackets that support the corrugated ceiling.

.ln carrying out mvv invention Iemployscetions or sheets of corrugated iron l; to form the ceiling, which are supported upon brackets l),disposed at intervals in parallel planes with the direction otthe length of the structure. 'ihese brackets are in their general cross-section triangular or provided with two ledges l (l, except where the)v rest against the walls ot" the house or structure, in that case being formed with but one ledge or shelf l), the purpose of which is apparent. 'lhese brackets are each t'ormed with upward-extending parallel plates havingl between them a space or slot j', while the upper edges of said extensions or plates are extended into lateral flanges provided with openings wi, which teeeive plastering. i

'lhe spaces or slotsf of the brackets l) receive hinges or brackets E E', the lowerends ot which are formed one with a single arm Serial No. 303,974y tNo modetl or flange t, while the other is provided with two fianges or arms It', which take in the spaces o ot the brackets under the shelves or ledges Il i). 'lhe vertical portions ol' thesusponders or hinges E E are twisted so as to cause one portion to stand in a plane at right angles to the other portion, thus permitting the pper portion to rest sidewise against and be readily secured to the tloorioists overhead. L'pon the lateral lianges of the extensions ot' lthe brackets l) at their ends are secured narrow plates or bars c, having` coincident apertures with apertnresot' said tlanges, said plates or bars et't'ecting the initial holding together of the brackets.

Along the walls of the structure are disposed angular plates 71, at the rear and front resting' upon the narrow plates or bars e, it may be, while those at the sides `t'esti dir-eetl)v upon the brackets, or, rather, upon their u pward-extending plates and thelateral lianges. These angular plates prevent communicating to the walls of dampness in ease of the saturation of the cement filling, presently described, which would occur from the use of water in the event ofthe building taking tire.

C is a cement filling introduced above the corrugated ceiling to a suitable depth, and into which the ,joistsare embedded to prevent` the communicating of the tire to the next iloor or story. ln the upper surface ot' this filling of cement are formed gutters ,r/ 5;, at suitable intervals apart, to drain or earrbr oil' the waste water, the same passing otif at the rearthrough short nozzle-like spouts (i, which are provided with caps i. This, however, is not permitted until the extingnislnnent of the tire, the caps l being kept on the spouts (i during the tire, the water thus being permitted to rise, say, a couple of inches above the tloor, at which point are applied inthe same or rear wall similar spouts ti (i, thereby keeping the water at that level.

lo the drain-spouts (l ti may be applied additional spouting leading' below to the ground. 'lhe spouts or pipes (i G', more particularly the former pipes, serve also, when not used as above pointed out', as a means ot` ventilation.

If desired, the brackets, instead ot being suspended by means of the hangers or suspenders, ma)Y be fastened directly to the ,joists lOO 'lhe hangers or suspenders, however, provide for space above the cement filling t`or ventilation or the circulation of air-currents in between the joists and in under the floor.

'l`he spaces provided by the arched surfaces of contact of the corrugated sheets or sections l with the brackets l) admit of' the decoration ot the latter thereat with various ornamental figures, as panels, rosettes, scrollwork, or any kind of' corrugated iron, also, the outer corrugated sheets or sections of iron forming the ceiling maybe lined upon the inside or outside with tarred paper, thus preventing rust from steam, water, or dam p air. A stand-pipe may be disposed upon each floor for flooding the same in case of tire.

Having thus described my invention, what I claim as new, and desire to secure by Letiters Patent, is-

l. The tire-proof ceiling having` its corrugated iron sections or sheets restingnpon the ledges or she] ves of brackets, in combination with snspenders `or hangers having their inner ends adapted to enter said brackets and to take in under the ledges or shelves of' the brackets, their upper ends being adapted for connection with the floor joists above, substantiallhvv as set forth.

il. ln a tire-proof ceiling, the brackets having a ledge or shelf to support corrugated iron sections or sheets and npwardiy-ex tended parallel plates formed with lateral flanges at their upper edges, substantially as Set forth.

El. In a fil-@proof ceiling, the combination ot the corrugated ceiling plat'es or sheets, i

the hollow brackets having` ledges or shelves and their u|wardly-extended parallel plates formed at their upper edges with lateral flanges havingl apertures therein, the hangers or snspenders having lateral arms or flanges let into the brackets and taking in unerd the ledges ot said brackets and having their upper ends adapted for connection tothe floor-joists, the fillingl of cement, and 'the angular plates applied to the wallsand between the same and theeement filling, substantially as speeied.

l. In a fire-proof ceiling, the combination of the corrugated iron sheets or sections, the brackets supporting said sheets or sections, the suspenders or hangers for said brackets, and the cement filling having gutters at intervals in its upper surface, and the outlet spouts or pipes taking the waste water from said gutter, substantially as specified.

5. In a fire-proof ceiling, the Combination of the corrugated iron sheets or sections, the brackets supporting said sheets or sections, the Suspenders or hangers for said brackets, the filling of cement, thenozzleslikc spoutsor pipes having caps applied to their outer dis chargingends,and the additional similar pipes or spouts arranged above the next thior, substantially as set forth.

In testimony whereof I aflix mv signature in presence of two witnesses.
